messagebox after add "isRequired" property (empty)
messagebox without "isRequired" property

Did you try putting boolean value into quotes?

@Juhas: nie działa nadal

Gdzie to renderujesz?

Z szybkiego researchu isRequired zostało dodane w wersji 1.3 adaptive cards, może klient renderujący nie wspiera wersji 1.3?

@some_ONE: wszystko jasne, emulator na którym robie nie wspiera tej wersji. dzięki
